Application filed September To all whom it concern:

Be it known that T, WILLIAM F. CREMEAN, a citizen of the United States,residing at Toledo, in the county of Lucas and State of Ohio, haveinvented certain new and useful Improvements in Car-Door Arrangements,of which the following is a specification.

This invention relates to a door arrange ment for railway cars or thelike and has among its objects to provide an improved arrangement ofdoor-supporting mechanism. Another object is to provide adoor-supporting mechanism wherein the door may be supported in partlyclosed or in fully closed position. Another object is to provide adoorsupporting mechanism having a plurality of door-supporting hooks,one arranged to support the door in one position and another to supportthe door in another position. A further object is to provide a pair ofdoor supporting hooks arranged to swing in parallel planes and hingeupon a common pivot point, one of the hoolzs being longer than theother. A still further object is to provide a door-supporting mechanismemploying a plurality of door-supporting members, one of said membersbeing provided with a fulcrum pin adapted to accommodate a doorpryinglever. A still further object is to provide a pair of correlateddoor-supporting hooks so arranged that one hook may be actuatedindependently in one direction and the other hook actuated independentlyin the opposite direction. Vifith these and other objects in view, theinvention consists of the formation, combination and arrangement ofparts, as will be herein described, and particularly pointed out in theap pended claims.

In the accompanying drawings, which show a preferred form of theinvention, Figure 1 is a fragmentary side elevational view of the sideof a car, showing the lower or hopper portion thereof and in connectiontherewith, a door arrangement constructed in accordance with theprinciples of the present invention. This figure shows but half of theordinary hopper, such as is provided for cars of the type depicted, butit will be understood th t duplicate portion of such a hopper is oraarily provided. Figure 2 is a transverse vertical sectional viewthrough the lower portion of the hopper, taken on the line 2-2 ofFigure 1. Figure 3 is a transverse horizontal section 2, 1922. SerialNo. 585,845.

through the door-supporting hooks, taken on the line 33 of Figure 1.Figure 4 is an oblique sectional view taken through the pivot point ofthe door hooks on the line 4 l of Figure 1. Figure 5 is a fragmentaryside elevational View, showing a modified form of the outermost hook,this view being similar to Figure 1.

Referring to these drawings, a fragment of the side of the car isindicated at 1, and the lowermost portion of the chute plate isindicated at 2. The lowermost edge of the side 1 may be formed along aninclined line as at 3 to define the plane of the hopper dischargeopening. A reinforcing angle l may be secured to the lower edge of theside plate 1, as by means of rivets 5. This angle has an inturned leg 6against the lower face of which the door 7 may seat when closed. Someclearance is shown in the drawings between the top or inner face of thedoor 7 and the lower face of the leg 6 of the angle, but such clearanceis necessary in order that too great nicety is not required in theworkmanship. A transverse stilfening angle 8 may extend across the carat the lowermost edge of the chute plate 2, and to this may be securedthe body hinges 9. Cooperating with the body hinges 9 are door hinges10, which are secured as by means of rivets 11 to the under face of thedoor. The hinge pintle is indicated at 12.

The door 7 may be of any type and is indicated in the drawings as beingformed of a steel plate having marginal flanges 13 and 14 along thehinged edge and along the free edge of the door respectively.

Extending transversely of the car across and secured to the under faceof the door 7 is a door stiffening member or door beam 15, this beingformed in the present embodiment of a channel iron which is shown assecured to the door'plate by means of rivets 16. This channel may extendslightly beyond the outermost edge of the door and preferably hassecured to its outer end a reinforcing angle iron 17. This angle iron asshown is riveted through one of its legs to the web of the door beam bymeans of rivets 18 while the other leg of the angle is riveted to thedoor plate by means of a rivet 37. The angle iron 17 is provided tolocally stiffen and reinforce the door and the door beam, and also toprovide a seat beneath which door-supporting members may extend and withwhich said members may supportingly engage. The door is arranged to beheld in either partly closed or in fully closed position. a pair of doorhooks 19 and 20 are provided, these being pivoted to the car body at acommon pivot point 21. A bracket 22 which overlies the pivot ends ofthese hooks has cast thereon an integral spool 23 upon which the hooksare positioned, the eyes of the hooks being of a suitable size tooperate upon the periphery of the spool 23. A rivet 24 is shown aspassing through the spool 23 and the car side 1, thereby holding thebracket 22 against the car side and holding the hooks in position uponthe spool 23. A cam 25 may also be pivoted between the bracket 22 andthe car side to hold the hooks in engaged relationship with the door. Asimilar spool construction may be employed for this purpose a rivet 26passing through this spool and through the car side. An additional rivet27 may be employed to affix the bracket to the car side.

The hooks 19 and 20 are arranged to swing in parallel planes and it willbe noted that the hook 19 is longer than the hook 20, or in other wordsthat the supporting ledge 28 thereof is at a lower elevation than thesupporting ledge 29 of the hook 20. By this means, the door may besupported in a partly closed or a fully closed position, depending uponwhether the hook seat formed by the horizontal leg of the angle 17 ispositioned upon the ledge of the hook 19 or upon the ledge of the hook20.

The hook 19 is preferably located outside of the hook 20, not only inorder that the bending moment in the. door beam and in the angle 17 maybe reduced as a result of the shortening of the leverage, but also thatthe outermost hook may be accessible for the preliminary support of thedoor, it being the practice to lift such doors to the preliminaryposition by hand. This arrange ment of the hooks also permits ofadvantageously forming upon the outer face of the hook 19 a fulcrum suchas the boss 30. Upon this fulcrum may be positioned a detachable lever31 whose innermost end may be inserted beneath the horizontal leg of theangle 17 thereby enabling the door to be conveniently and effectivelypried from a partly closed to a fully closed position. In the embodimentshown in Figure 5, the boss 30 is at a lower elevation than in theembodiment shown in Figure 1, so that the innermost end of the lever 31may be positioned beneath the lower flange of the channel 15 in forcingthe door shut.

By the provision of the two hooks with supporting ledges at differentlevels, the lever 31 may be fulcrumed upon one of the hooks and the doorpried up, the other hook being thus left free to swing into supportingTo this end,-

position beneath the door. In a previous on a hook having two ledges,one of which is adaptedto support the door in a partly closed and theother in a fully closed position. In this early arrangement, it is oftendiflicult to swing the hook when the lever is bearing down upon 'it. Thepresent arrangement overcomes this difficulty.

Itis desirable in many instancesthat both hooks should be withdrawn fromengagement with the door at the same time, and it is particularlydesirable that when the hook 19 is swung back the hook 20 should also beswung back-with it, but it is also desirable that the hook 19 should becapable of being swung forward without hindrance from the hook 20. Tothis end, an interior locking arrangement is provided between the twohooks. This is formed by means of the lug 32, which is cast upon theinner face of the hook 19 and so disposed that it will engage a flangeof the hook 20 when the hook 19 is driven back'as by means of blowsdirected against the boss 30. It will thus be seen that when theoutermosthook is driven back, the innermost hook will also be drivenback, but there is sufficient clearance between the lug 32 and thecontactin flan e of the hook 20, as at 33, so that be ore t e lug 32engages this flange,'the hook 19 will have been moved back some slightdistance. This is desirable in order that the leg of the angle 17forming the seat for the hooks shall not strike the ledge of the hook 19when the loaded door is released from fully supported position upon theledge of the hook 20. When being closed, the doors will first be swungupwardly sufiiciently to permit the hook 19 to be driven into positionbeneath the line of swing of the horizontal leg of the angle 17 afterwhich they are forced to fully closed position and the hook 20 is driveninto supporting position beneath this leg of the angle. The cam 25 willhold both hooks in such positions. Each hook may advantageously beformed with a web 3 1 and a marginal flange 35, and it is preferablethat the web should in each 'in stance be along one side of the hook andthat the flange should outstand from the web toward the outer face ofthecar. This is not only desirable, in order to provide for the interiorlocking features heretofore described, but it also lends itself Well tothe manufacture of these hooks and provides shoulders in all directionsagainst which operating implements may be applied.

I have thus described a preferred embodiment of my invention. Otherembodiments are contemplated within the scope of the appended claimswithout departing from the spirit thereof.

What is claimed is:

1. In a car door arrangement, the combiembodiment I have shown a fulcrumformed nation with a drop door hinged to the car body, of a pair ofhooks pivoted to the car body and arranged to swing in parallel planesinto supporting engagement with the door, one of said hooks being ofgreater length than the other and being arranged to support the door ina position different from that which said door occupies when supportedby the other hook.
